function tsprint(y,cstruc,varargin)
% PURPOSE: print time-series matrix or vector with dates and column labels
%---------------------------------------------------
% USAGE:     tsprint(y,cstruc,begp,endp,vnames,fmt) 
%        or: tsprint(y,cstruct,vnames), prints entire series with names
%        or: tsprint(y,cstruct), entire series, no variable names
%        or: tsprint(y,cstruct,fmt) entire series, using fmt
%        or: tsprint(y,cstruct,vnames,fmt) entire series w/names and fmt
%        or: tsprint(y,cstruct,begp,endp) partial series no names or fmt
% where: y       = matrix (or vector) of series to be printed
%        cstruc  = a structure returned by cal()
%        begp    = the beginning observation to print
%        endp    = the ending period to print,
%        vnames  = a string matrix of names for a header (optional)
%                  e.g. vnames = strvcat('y','x1,'x2','x3');
%        fmt     = a format string, e.g., '%12.6f' or '%12d'
%---------------------------------------------------
% e.g.    cstr = cal(1980,1,12);
%         tsprint(y,cstr,13,24), would print data for 1981
%
%     or: tsprint(y,cstr,ical(1981,1,cstr),ical(1981,12,cstr)),
%         which would print the same data for 1981
